What do you think, Ynaig?...

I'll bet it's some version of the same cement that CalEarth uses for their wall structures.. Looks like the walls and floor are both made of the same material.

CalEarth is a great site, I encourage you to get and read the originator's book :-).

Good Health,

Ladylove :-)

PS: Perhaps Ynaig can give her opinion/experience on using cob (Or something like it) for this kind of application?

PPS: Konfetti Bomber, what materials are local to your area? Tweet
